WHAT IT DOES

What restart_service does on OPNsense MCP Server

AI agents invoke restart_service to trigger actions in OPNsense MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why restart_service is rated High

This tool executes a service restart operation on a firewall, which is a consequential action affecting network operations and availability. While not destructive (the service state is reversible) and not financial, it is Execute-category because it triggers external system operations whose effects depend on which service is targeted.

From the tool's definition Tool name is 'restart_service' and description states it will 'Restart an OPNsense service'. Restarting a service is an operational action that triggers external execution on the firewall system.

RECOMMENDED RULE

The rule that runs restart_service safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OPNsense MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For restart_service, this is the rule to start with:

restart_service Rate-limited

restart_service stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
